The PREFER part signals the preference of passing by reference, but if the argument is not a variable, it should behave as if the parameter was defined with ZEND_SEND_BY_VAL and keep quiet, just as for regular ZEND_SEND_BY_VAL parameters. Test script: --------------- <?php error_reporting(32767); current($arr = array(0 => "a")); /* Strict Standards: ... */ current(array(0 => "a")); current($arr); ?> Actual result: -------------- Strict Standards: Only variables should be passed by reference in filename on line 5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55754&edit=1
